Horizontal ridge augmentation with allografts has attracted notable attention because of its proper success rate and the lack of disadvantages of autografts. Corticocancellous block allografts have not been adequately studied on humans. Therefore, this study evaluated clinically and histomorphometrically the increase in ridge with after horizontal ridge augmentation using corticocancellous block allografts, and the implant success after 12 to 18 months post-implantation. In 10 implant patients (3 women, 7 men, 45 years old on average), defective maxillary alveolar ridges were horizontally augmented using freeze-dried bone allograft blocks...

The fracture strength of prosthetic abutments with different sizes and combinations to support a 5 implant milled framework with distal extension was tested. Prosthetic abutments with different dimensions (4.8 mm diameter mini-conical abutment and 3.5 mm diameter micro-conical abutment) were screwed to 5 threaded implants. The following groups were divided (n=3): G1 with 5 mini-conical abutments (standard size), G2 with 5 micro-conical abutments (small sized), G3 with a combination of 3 small sized abutments and 2 standard sized abutments, and G4 with a combination of 2 small sized abutments and 3 standard sized abutments...

For decades titanium has been the preferred material for dental implant fabrication, with mechanical and biological performance resulting in high clinical success rates. Tshese have been further enhanced by incremental development of surface modifications aimed at improving speed and degree of osseointegration and resulting in enhanced clinical treatment options and outcomes. However, increasing demand for metal-free dental restorations has also led to the development of ceramic-based dental implants such as zirconia...

The association of Morse taper implant-abutment design with the use of a smaller abutment diameter (platform-switching) may improve dental implant success rate and prevent peri-implant bone loss. The aim of the present study was to histologically and histomorphometrically evaluate the behavior of peri-implant tissues around an implant with a conical connection associated with platform-switching. A platform-switched Morse-cone connection implant was inserted in the left posterior mandible in a 61-year-old patient...

To ensure that similar primary implant stability measured by resonance frequency analysis (RFA) could be obtained in different jawbone densities by using a specific surgical drilling protocol and, to correlate those RFA measurements with factors related to the implant design, width and length, we are performed a one-year prospective clinical study was carried out using 27 subjects. A total of 67 hydrophilic titanium implants were placed using a standard two-stage implant placement protocol. The bone type at each implant site was determined by evaluation of a preoperative, high-resolution cone beam computed tomography (CBCT) scan...

The most common cause of peri-implantitis is the accumulation of plaque and the formation of a biofilm on the implant surface. Terminating the development of the disease requires the biofilm to be removed from the implant surface. This paper describes two cases of severe peri-implantitis lesions treated through surgical approaches. Complete mechanical debridement with a round titanium brush was mainly performed to detoxify and modify the affected implant surface. A regenerative approach was then performed. In both cases, the surgical procedure was effective in arresting the peri-implantitis, and clinical re-entry revealed uneventful healing of the existing bone defect...

Clinical decisions regarding the stability and osseointegration of mandibular implants positioned using the bone expansion techniques are conflicting and limited. The objective was to evaluate the stability of implants placed using two surgical techniques, selected according to the initial width of the mandibular posterior edentulous ridge, with D3 bone density, during a 12-week period. Fifty-eight implants in 33 patients were evaluated. Thirty-two implants in 24 patients were positioned using the osteotome expansion technique, and twenty-six fixtures in 17 patients were installed using the conventional drilling technique...

Implant surfaces are continuously being improved to achieve faster osseointegration and a stronger bone to implant interface. This review will present the various implant surfaces, the parameters for implant surface characterization, and the corresponding in vitro human cell-based studies determining the strength and quality of the bone-implant contact. These in vitro cell-based studies are the basis for animal and clinical studies and are the prelude to further reviews on how these surfaces would perform when subjected to the oral environment and functional loading...
